First off, can you check the log files for errors when you start up Apache? It might be complaining, and it will give very useful information if it does..

Secondly, are you making similar changes to the SSL side of things? MOD_SSL is handled via a different config file, and if you're trying to access these sides of things on port 443, you're not going to get all the different sites working.

Now you can serve the same content in the manner YOU were trying to do as well. You just have to set the correct document root for domain number 2. In your example the doc root contains a backslash that it shouldn't if the idea is to serve the same content as domain 1.
